Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a device for coupling frame members of a ceramic sash frame member or a frame member with other parts such as a crescent lock and a hinge.

[Prior art] As a sash, conventionally, aluminum, steam,
The plastic and wooden ones are often used, and the ceramic ones are rarely used at present.
However, since ceramics are excellent in corrosion resistance and fire resistance, a ceramic sash is expected as a sash to be used where such characteristics are particularly required.

[Problems to be Solved by the Invention] However, the ceramic framework has various problems in the developing stage. One of them is a problem of connection between frame materials during frame work, or a problem of connection between frame material and other parts such as a crescent lock and a hinge. That is, for example, when the frame members are joined together by tightening a fastening member that penetrates through a hole formed in the wall plate of the frame member, the ceramic has a property of being hard but brittle, and the hole is usually precisely finished. Since it is not a thing, there are fine irregularities and notches on the inner surface and the peripheral edge of the hole, and when tightening force is applied here, cracks and cracks will occur from here,
It may not be possible to connect desired frames or attach parts.
An object of the present invention is to provide a coupling device that can solve such problems.

[Means for Solving the Problems] In the present invention, in various connecting portions of a ceramic sash frame member, a fastening member is passed through a hole of a wall plate of the ceramic frame member, and the wall plate is separated from the hole. It is a joining device in a ceramic sash frame member formed by fastening the fastening member via a seat plate having a leg portion that abuts.

As a concrete connecting part, a connecting part formed by abutting other ceramic frame members at both ends of the ceramic hollow frame member in an orthogonal manner, a wall plate surface of the ceramic frame member, and a crescent tablet. There are joints such as hinges.

[Operation] In the coupling device of the present invention, the tightening force at the time of coupling is transmitted to the ceramic frame member through the leg portion of the seat plate that is in contact with the portion apart from the through hole.

[Embodiment] An embodiment of the present invention will be specifically described below with reference to the drawings.

FIG. 9 is a front view showing a typical example of a sliding window to which the present invention is applied. In the figure, 1 is a window frame, 2 is an upper frame, 3 is a lower frame, and 4 is a vertical frame. Further, 5 is an external shoji, 6 is an internal shoji, 7 is an upper frame, 8 is a lower frame, 9 is a vertical frame, and 10 is an assembling frame. 11 is a crescent tablet.

Then, the coupling device of the present invention is applied to the fastening portion A of the window frame 1, the inner portion, the fastening portion B of the outer shoji 5, 6 and the fastening portion C of the crescent lock 11.

FIG. 1 is a perspective view showing a connected state of an upper frame 7, a vertical frame 9 and a summing frame 10 which are ceramic frame materials of the inner shoji 6, and FIG. 2 is a cross sectional view of a right corner portion of FIG. It is shown. Each ceramic frame member has a hollow portion, and a vertical frame 9 and a summing frame 10 are respectively abutted on both ends of the upper frame 7 in an orthogonal manner, and a fastening pipe 12 arranged in the hollow part of the upper frame 7 is formed. , Bolts arranged through the holes 14 provided in the upper portions of the wall plates 13 of each of the vertical frame 9 and the summing frame 10.
The above three members are fastened by tightening the bolts 15 using a fastening member configured by screwing with 15. At this time, the leg 16 is formed between the bolt 15 and the wall plate 13.
Seat plate 17 adapted to abut the surface of the wall plate 13 away from 14
Intervene.

FIG. 3 is a modification of FIG. 2, in which the fastening pipe 12 is eliminated and the whole is a bolt 18, which is fastened by a nut 19.

FIG. 4 is another modification of FIG. 2, in which (a) is a cross-sectional view,
(B) shows a vertical sectional view. In this example, the wall board 13 of the vertical frame 9
And a spacer 21 between the upper and lower lateral walls 20 of the hollow portion of the upper frame 7.
And the tightening force of the bolt 15 is received in cooperation with the seat plate 17 to more strongly prevent cracks and breaks.

FIG. 5 shows another modification of FIG. 2 in which the end of the upper frame 7 is connected to the vertical frame 9
The same effect as in the case of FIG. 4 is exhibited by swallowing it.

FIG. 6 shows a crescent lock 11 on the summing frame 10 of the internal shoji 6,
Further, in this embodiment, the crescent receiver 23 is attached to the summing frame 10 of the shoji screen 5.

The crescent lock 11 has a hole 14
It is fixed with bolts 24 via a seat plate 17 having a leg portion 16 that abuts at a position away from. The fixing with the bolt 24 is performed by screwing the back seat plate 26 fixed with a screw 25 on the hollow side of the dressing frame 10. Like the seat plate 17, the back seat plate 26 also has a leg portion 27 that abuts at a position apart from the hole 14.

Further, the crescent receiver 23 is attached by bolts 28 to the inner wall forming the hollow portion of the outer summing frame 10. Specifically, the base plate 22 having a shape corresponding to the seat plate 17 and the base portion of the crescent receiver 23 are integrated, and the back seat plate 26 having the same shape as the back seat plate 26 is applied to the hollow portion side and screwed. There is.

FIG. 7 shows a state in which the door 29 is connected to the frame 30 with a hinge 31. Each piece of the hinge 31 uses a seat plate 17 and a back seat plate 26 having legs that come into contact with each other at positions apart from the holes, and screws 25
It is screwed and fixed by.

FIG. 8 shows various modifications of the seat plate used in the present invention,
(A) is a circle, (B) is a U-shape, and (C) is a table-top shape. Of course, these are typical examples, and other various shapes are conceivable depending on the design of the required portion.

[Advantage of the Invention] The present invention provides a fastening force of a fastening member through a seat plate (or a back seat plate) having a leg portion that abuts a portion of the ceramic sash frame member that is apart from a hole passing through the fastening member. Since it is transmitted to the ceramic frame material, the tightening force is less likely to cause cracks or cracks from the holes provided in the fastening member.
